does that really help? I have had llms fumble pretty simple stuff in html/css and probably that's what there's more information on the internet, while with simple packages/languages with clear cut semantics it seems to be much better, even if off some samples pasted into context.

[edit] the case was simply, write me an html landing page, with a navbar, a content area and a footer, make sure the content on each area doesn't extend beyond 1200px wide , make each container centered (paraphrasing)
